  • About This Answer

    To calculate the exact amount of property tax you will owe requires your property's assessed value and the property tax rates based on your property's address. Please note that we can only estimate your property tax based on median property taxes in your area. There are typically multiple rates in a given area, because your state, county, local schools and emergency responders each receive funding partly through these taxes. In our calculator, we take your home value and multiply that by your county's effective property tax rate. This is equal to the median property tax paid as a percentage of the median home value in your county.

New Hampshire Property Taxes

New Hampshire is known as a low-tax state, but homeowners in the Granite State might disagree with that characterization. While the state has no personal income tax and no sales tax, it has the third highest property tax rates of any U.S. state, with an average effective rate of 2.05%.

Likewise, in dollar terms New Hampshire’s property taxes also rank among the top three: the median property tax paid by homeowners in New Hampshire is $4,927. That means about half of all New Hampshire home owners pay more than $5,000 annually in property taxes.

How New Hampshire Property Taxes Work

New Hampshire has both state and local property taxes. In fact, any given property can pay up to four different property taxes: a town tax, a local school tax, the state education tax and a county tax.

To determine the amount on which to base taxes, local assessors conduct annual appraisals. The goal of these appraisals is to calculate the full market value of the property. In general, assessors do not visit properties, but instead use mass appraisal techniques to determine property values based on market and property data.

That is an inherently imperfect process. Homeowners who disagree with their home’s valuation can file an abatement request. That will general lead to a review of valuation, and a possible refund of taxes paid.

Likewise, the state of New Hampshire recognizes that different areas have slightly different appraisal procedures. It annually “equalizes” values between counties, using market data to apply a ratio that balances values between all areas. That ratio is used to determine the state education tax rate, which varies from city to city, as described below.

New Hampshire Property Tax Rates

Tax rates in New Hampshire are determined by a number of local government authorities, as well as by the state of New Hampshire. Towns, school districts and counties all set their own rates based on budgetary needs. Rates are expressed in mill rates. One mill is equal to $1 of tax for every $1,000 in assessed property value.

The state of New Hampshire collects a state education tax. The rate is around 2.5 mills, but varies from county to county depending on the equalization ratio described above.

When comparing rates between counties, it is useful to look at effective property tax rates and not mill rates. Effective property tax rates are property taxes paid as a percentage of home value. The table below shows the average effective property tax rate for every New Hampshire county.

Rank County Property Tax Rate School Rating Crimes Per 100k People

Methodology

Our study aims to find the places in the United States where people are getting the most for their property tax dollars. To do this we looked at school rankings, crime rates and property taxes for every county.

As a way to measure the quality of schools, we calculated the average math and reading/language arts proficiencies for all the school districts in the country. Within each state, these schools were then ranked between 1 and 10 (with 10 being the best) based on those average scores.

For each county, we calculated the violent and property crimes per 100,000 residents.

Using the school and crime numbers, we calculated a community score. This is the ratio of the school rank to the combined crime rate per 100,000 residents.

We used the number of households, median home value and average property tax rate to calculate a per capita property tax collected for each county.

Finally, we calculated a tax value by creating a ratio of the community score to the per capita property tax paid. This shows us the counties in the country where people are getting the most bang for their buck, or where their property tax dollars are going the furthest.
